2 Claims.

My invention relates to a closure means for securing a bottle cover or cap closure or for securing cloth or paper bags containing material of any kind closed. The invention is applicable to skirted bottle closures, such as are commonly used in connection with milkl bottles, for sanitarily protecting the lip of the bottle. The invention particularly has for its object to provide a simple, easily released fastener for binding the closure to the neck of the bottle, yet one that is so formed as to prevent unfastening except upon proper manual manipulation to produce unfastening.

A pliable, relatively light-weight wire is disposed about the neck of the bottle or gathered parts of the open end of a bag so as to locate end portions of the wire in overlapping relation and dispose the overlapping portions one above the other and in close contact with each other and the surface of the part to be secured or closed. The central parts of the overlapping portions are bent to form open-ended loops. The parts of the loop located contiguous to the closure member are then twisted in a direction to press each end of the wire against the side of the other overlapping portion to produce a closed double loop substantially circular in form. The twist of the quadruple crossing strands will tighten and retain the tautness of the body part of the wire about the closure member and also cause the very ends to press into the material of the closure member. The quadruple twist prevents loosening of the fastener and thereby enables the use of a small or relatively line and flexible wire. The wire may be readily loosened by reverse rotation which operates to swing each end of the wire away from the other over-lapping portion to cause the ends of the Wire to engage the curved end portions of the said body part of the wire and hold the ends of the wire as the loops are further moved in the reverse rotation. The parts of the loop will eventually separate from each other, and the wire will ordinarily drop from the closure member, or by a slight outward pull to bend the body part of the wire, the wire may be removed. The doublestranded loop forms a handle that enables easy and convenient untwisting of the interengaging portions.

To illustrate a practical application of the invention, I have selected a fastener for a milk bottle cover or cap and will describe the fastener hereinafter. the accompanying drawings.

Fig. 1 illustrates a perspective view of a fastener and the closure member that is secured thereby. Fig. 2 is an enlarged view showing the parts CJI The fastener selected is shown inA 1936, Serial No. '77,093 (Cl. 21S-94) of thewire slightly loosened or separated fromv i' view of the 'mechanism' illustrated in Fig'. 3. Fig.

5 illustrates an end view of one of a pair of gripping means for holding the over-lapping portions of the wire fastener against the closure member as the portions slide relative to each other when the closure or cap is secured by the fastener.

In the form of construction shown, the bottle I is provided with a sanitary cap 2 for covering the top of the bottle. The wire closure fastener 6 is located around the skirt 3 of the cap or cover 2. The wire is of sufficient length to provide overlapping end portions 5 and I that are centrally bent to extend to and from the bottle in the form of an open-ended loop. One over-lapping portion, such as the portion 5, is located beneath the other over-lapping portion, and each end part of the wire is located against the skirt 3 and in contact with the over-lapping portion terminating in the other end part of the wire. The loops are then rotated while the contacting parts of the over-lapping portions are maintained in their relation to each other. The twist of the parts of the wire operates to draw the body'part 6 tightly against the skirt 3.

The end parts 8 and 9 of the body part of the wire are curved as they form into the twist. The curved end part 8 of the wire forms a continuance of the body part 6 of the wire to the loop part I2, and the curved end part 9 of the body part of the wire continues into the loop part I3. The loop part I2 terminates in the end part I4 of the wire, and the loop part I3 terminates in the end part I5 of the wire. When, therefore, it is desired to remove the closure or cover of the bottle, the loop parts are rotated in a reverse direction which causes the end part I5 to engage the curved part 9, it being directed thereto by the curved portion I6 of the overlapping part 5, and the end part I4 to engage the curved part 8, it being directed thereto by the curved portion I'I of the over-lapping part 'I. The end parts of the wire are thus held as the loop parts I2 and I3 are reversely rotated about the same number of turns that produced the twisted connection. The loops are thereby separated and, by reason of the exibility of the wire, the wire will ordinarily drop from the skirt of the closure member, or the wire may be removed from the skirt by slightly spreading the loops or by a slight outward pull of the loops to separate the end part I4 from the part 8 and the end part I5 from the part 9,

'Ihe fasteners are shaped by means of a pair of levers I8 and a rotatable post I9. The levers I8 maybe pivotally supported by brackets 20 the Wire against the skirt.

provided with arms 2l having rollers 22. The ends 23 of the levers are brought together by means of a. cam 24Vthat engages thev rollers 22. Ther ends 23 of the levers are provided with notches 25 to engage and partly enclose the overlapping portions of the wire and draw the sides of the open loops of the wire towards eachother and to the skirt 3 of the cap and engage and press the over-lapping portions and the` end parts I2 and I3 of the wire and draw the body part 6 of The closed loops I4 and I are formed by rotation of the post I9.

The post I9 mayl be connected to a shaft 26 thatextends through `a sleeve 21 on-which is mounted the cam 24. The cam 24 may be rotated by the beveled gear wheels29, while the shaft 26 and the post I9 may ybe rotated by the beveled gear wheels 30. The beveled gear wheels 29 and 30 may be driven by a suitable source of power.
